Embodiment Construction

[0029] In the figures, identical parts are provided with the same reference numerals.

[0030] figure 1 The connection area of ​​the handle 1 of the electric toothbrush is shown, which is intended for connection with the brush part 13 according to the invention shown in FIG. 3 .

[0031] The handle 1 comprises a plastic casing and all parts required for operation, such as electric motor, transmission, accumulator or battery, controller and the like. These components are located in the housing and are not shown.

[0032] as in figure 1 As shown in , a shaft 2, in particular made of metal, protrudes directly from the handle 1, which shaft can oscillate torsionally about its longitudinal axis at a high frequency of about 260 Hz. That is to say, the shaft 2 is driven by an electric drive mechanism to vibrate. Other oscillating movements, for example along the axis 3 or combinations thereof, are also possible. This vibrational movement is directly transferred to the tufts 50 o...

Abstract

The invention concerns a brush part (13), which can be placed upon a shaft (2) of a handpiece (1) of an electric toothbrush and is designed so that it can be detached therefrom. Said brush part comprises a bristle area, a brush shank (12) and an attachment part (11) situated inside the brush shank (12). This attachment part (11) has a first spring element (35) and a second spring element (30) that act upon the shaft (2) when the brush part (13) is placed upon the shaft (2). This results in a play-free connection between the brush part and the shaft that enables the transmission of even high vibration frequencies.

Description
